MARKING APPARATUS.

Specification of Letters Patent.

Patented March 19, 1907.

Application filed March l0, 1906. Serial No. 305,223.

To all whom it may concern:

Be it known that I, EDWIN M. SoHANTz, a citizen of the United States, and residing at Zimmerman, Greene county, State of Ohio, have invented certain new and useful Improvements in Marking Apparatuses; and I do declare the following to be a clear, full, and exact descri tion of the invention, attention being calle to the accompanying three sheets of drawings, with the reference characters marked thereon, which form also a part of this specification.

This invention relates to a new and useful apparatus to be used for the purpose of locating marks upon lumber and sawmill stufflike boards and planks, for instance, or veneerthe object of such marks being to indicate by their position the points and lines at and along which the lumber is to be cut up subsequently and reduced into smaller pieces, so-called mill or dimension stuff.

The primary object of this present invention is to show to the operator automatically what sizes of reduced stuff are required according to orders on hand, so that he may locate the marks which indicate subdividinglines accordingly, and as these smaller sizes are controlled by the size of the larger board to be subdivided or by the presence and location of defects thereon which are to be avoided, considering also at the same time the desirability to reduce the lumber in the most practical and profitable manner by favoring orders requiring larger sizes or preference as to time and by reducing all non-avoidable waste. Since the smaller one of the two controlling dimensions of the lumber to be reduced-to wit, its widthmcontrols and limits the location of the marks for subdivision to a larger extent thanA its length, I determine and locate on the larger piece of lumber the width for the required reduced stuff first and with reference to and as controlled by the width of such lumber or by the available defect-clear space thereon, after which the marks defining length of the pieces are also located, .this more extensive dimension or length of the lumber usually permitting more liberty and a larger range for selection.

To be more specific, I now outline in general the intended operation of my apparatus and whereby the manipulation of certain parts of it for determining the first one of the two dimensions to which the stuff is to be reduced, and which first dimension in this case is the width, operates also automatically to furnish to the operator other information which he must necessarily have for the purpose. This information relates first to the other dimension, complementary to the dimension first determined, and which other dimension is the length, and it shows what lengths are required at the width so determined, such indication being rendered perceptible by the visible operation of a signal which acts in conjunction with or appears opposite a particular figure on a scale or forms part of such a scale and against which scale the board to be marked for reduction rests. This information so conveyed automatically relates also to the orders to be filled, and by giving automatically the sizes' of a piece it shows simultaneously to the operator what sizes are wanted according to orders at hand, because the appearance of a length-indicating signal on the scale and opposite the lumber shows also at the same time that an order for a piece of that particular length and at the previously-determined width is on hand, while the non-appearance of any signal at such width would also mean that no orders are on hand for any length at such Width. In such case the operator simply continues the 1n anipulalion for determining width across the u' idth of the lumber until the operation of the manipulated parts causes the appearance of signals indicating length at another width and simultaneously a corresponding order. As soon as this occurs the particular marks or points for subdiyision according to the size and as indicated by the signals are located on the lumber, which size may also be noted in gures on the piece, after which the lumber is shifted to a certain normal position with reference to the scale, and the operation is repeated for marking out another piece adjoining the piece previously marked out. signals might be mechanical or electrical, and the latter method is chosen, the signals consisting more particularly of small electric-light bulbs arranged to form the scale referred to. It is obvious that such an apparatus is not necessarily limited to use in connection with lumber and may be used n connection with any other material of limited thickness and when the same is to be subdivided and cut up according to length and width.

In the following specification, and particularly pointed out in the claims at the end thereof, is found a full description of my in- The operation of thcse IOC' IIO

vention, together with its operation, parts, and construct on, which latter is also illustrated in the accompanying drawing, in which- Figure 1 in a sectional side elevation shows the apparatus with its parts in normal position. Fig. 2 in a similar view shows the parts adjusted with reference to the width of a board to be marked for subdivision. Fig. 3 is a top view of the apparatus with its parts in the position shown in Fig. 2. Fig. 4 is a front view. Fig. 5 is a sectional view taken at a plane back of the front view and parallel thereto it being substantially a cross-section taken on line 5 5 of Fig. 1. Fig. 6 is an enlarged sectional detail view of the complementary contact-pieces, showing at the same time a modified arrangement of them. Fig. 7 is an enlarged detail view of the markingarm, parts broken away. Fig. 8 is a diagrammatic view similar to Fig. 1 and shows at reduced scale a modified arrangement in multiple. Fig. 9 shows a detail view of a circuit-breaker or so-called Hasher used in connection with the electrical operation of my device.

In the drawing, 15 indicates a certain member, which I preferably call orderboard or order-carrier, because upon it the sizes of the required subdivided pieces are. determined according to length and width, as specified in orders on hand. This order-carrier is provided with plug-sockets arranged in rows lengthwise and transversely and spaced apart in each row in equidistant scale units, which units may beinches or fractions thereof. Further description of certain details of construction of this part will be given at the proper time. lt is supported in a position preferably horizontal and se as to be adjustable in this position with reference to the lumber to be handled. A frame 16 is provided with rollers 17 on its under side, which are litted to tracks 18, upon which the device travels during its adjustment. Any particular position of the same, as well as its adjustment and the extent of movement connected with such adjustment, is indicated by a pointer 19, Fig. 3, operating in conjunction with a scale 21, showing scale units corresponding to those in which the order-carrier is subdivided by the plug-sockets. A support for the lumber is arranged in a position convenient for the operator, the same consisting, preferably, of rollers 22 to facilitate shifting of the lumber, which occurs every time after a piece has been marked out.

23 is a scale showing length and against which the lumber to be marked is placed with one of its longitudinal edges while resting flatwise on rollers 18. For present purposes the graduations on this scale which correspond te those on the order-carrier and of scale 21 may indicate inches, although in reality subdivisions of inches may be added,

if required. In connection with each graduation on this scale there provided a signal 24, which, as before alluded to, consists of a small electric light, and the operation of which will be presently described. Back of this scale there is a bridge 25, arranged lengthwise across the machine and resting with its ends on the general frame of the same. The arrangement is such that the order-carrier 15 in its adjustment passes ha ek and forth under this bridge. Permanentlyattached contact-pieces 26 are provided on the under side of this bridge, yieldingly held in normal position by spring-pressure er gravity, there being one for each sign al-l amp of the scale. They operate in conjunction with complementary contact-pieces in form of plugs 27, which are inserted in the sockets of said carrier, removably carried to permit arrangement according to orders on hand. Thus, for instance, if an order is on hand for boards 'live inches wide and thiteen inches long a plug would be placed in a socket corresponding to these dimensions, and such being done for every order. For such lengths of which there are no orders no plugs would be inserted, so that there will be no aetion on the complementary contact-piece when the carrier is manipulated, and the corresponding lamp will not light up.

For manipulating the order-carrier l provide a handle 28, the manipulation beingl subject to the width of the board or to the width of apiece to be marked out thereon. Unless the pieces to be marked out are quite narrow or the lumber is of considerable width it is preferable to select and work up orders which suit the width of the lumber, thus dispensing with the necessity of also subdividing and cutting the lumber up lengthwise. The lower part of the handle is preferably pointed and serrated, as shown at 2%), Fig. 4, to permit it to be used for impression of marks when such becomes necessary.

The normal use is as follows: A piece of lumber to be subdivided is placed in position with one of its longitudinal edges against scale 23 and with its left end opposite the '/.eromark thereon. The order-carrier is moved forward from its normal position, the extent of the movement being equal to the width of the lumber, which width is determined by lowering the handle 2S and by placing the pointed part 29 of the same against the other longitudinal edge of the lumber, as shown in Figs. 2 and 3. Presuming now there was an order on hand for pieces five by thirteen inches, the lamp at the thirteen-inch mark of scale 23 will light up, because one of the plugs 27 on the prearra'nged order-carrier will come in contact with the contact-piece 26 on bridge 25 which corresponds to the lamp at the thirteen-inch mark of scale 23. The operator perceives now at once not merely that he has an order for pieces live lOO inches wide but the signal shows him also the length ofthe pieces, which length he now accordingly fixes on the lumber by placing a mark on it opposite graduation 13 on scale 23, using chalk or pencil for such purpose. In reality the operator is not burdened with the consideration of figures at all or their retention in memory. It is immaterial to him during manipulation of the apparatus what the actual sizes are to be. I-Ie merely adjusts order-carri er 15 according to the actual wid th of the lumber, using handle 28 and pointer 29 to determine this, after which he looks for the appearance of any lamp-signals. The appearance of a lighted lamp shows him that an order is wanted at a length indicated by the position of the signal, and opposite which signal he` now places a mark on the lumber. Should he desire, however, to ascertain the actual dimensions, as indicated by the position of a lamp-signal, for the urpose of writing them on the piece marked) out or for any other purpose, he can readily do so.

The width he nds on scale 21 as indicated thereon by pointer 19, which shows the extent of the movement of order-carrier 15 during its adjustment. The length he obtains from scale 23 by noting the graduation indicated by the signal. It may be that several signals spring up at a certain width. Thus, for instance, in the given case and in addition to the lamp at 13 lamps might light u showing orders at lengths of, say, eight, ifteen, twenty-six inches long, &c. In such case the operator uses his judgment as to what piece to select at the time, favoring longer pieces or such forming part of hurry orders. Should existing defects interfere with the marking out of a longer piece, he selects a shorter ,length, marking as close up to the defective spot as possible. `After a piece is so marked the lumber is shifted to the left to bring the previous mark opposite to the zero-mark on scale 23 unless the preceding piece reached close up to and was marked with reference to a defect in the wood which limited its length, in which case the operator starts on the other side of the defective spot, which latter is wasted. Should it occur after having adiusted the order-carrier according to the width of the lumber, and as such width is determined by pointer 29, that no signals show at the width of the particular lumber, then the pointer is pushed inwardly from the edge of the lumber, the operator watching at the same time scale 23 for the appearance of signals, after which, with the order-carrier in the newly-adjusted position, he proceeds with the marking as before. The same would be done if a defective edge would prevent use of the full width of the lumber. In such cases the lumber would also have to be cut on longitudinal lines to obtain the piece marked out. In placing the marks for these longitudinal lines the lower end of handle 28 is used to locate them, a pencil-mark being placed on the lumber opposite such lower end; or the pointed end itself may be used for the purose, a mark being impressed into the wood by striking the upper part of the handle.

It may also occur that some lumber may come at widths in excess of the width of the pieces wanted for the orders.` Thus, for instance, a piece of lumber might be nine inches wi de, whereas the largest width in the orders on hand is ve inches. This would permit the marking out of two or more pieces side by side--as, for' instance, two pieces, one five and the other four inches wide, &c. This requires possibilty of manipulating handle and pointer independently and without acting on the order-carrier, because after the width of the first piece has been determined the ordercarrier must be returned to its normal position at Zero with reference to scale 21, after which the pointer must be moved out independently and without affecting the normal position of the order-carrier until it has passed over the width of the space previously marked out, after which the pointer and order-carrier may again move together, this time for determining the width of the piece to be marked' out alongside of the piece marked before. For such purpose the arm on which handle and pointer are carried consist of two parts-a tube 31, attached to the order-carrier, and a rod 32, fitted into the former in a manner leavingitfree to slide as well as to turn. Normally the two are engaged, a pin 33 on rod 32 being held by means of a spring 34 to occupy one of the spaces provided in the dentated edge 35 of a slot 36, provided in tube 31. If it is now desired to move the pointer without affecting the position of order-carrier 15, it is only necessary to turn rod 32 by means of handle 28 in a manner to move pin 33 into slot 36, after which the pointer may be moved alone without affecting the position of the order-carrier. Spring 34 turns the rod again to normal position, one end of it being attached to this rod, the other to a block 37, prevented from turning by sliding inslot 36a. The inner end of the arm, which carries the handle and pointer, is attached ina manner to cause the front end to assume a normally elevated position, so as to be out of the way when not in use-as, for instance, during the time when the lumber is placed or shifted. For such purpose the inner end of tube 31 is hingedly attached at 38, and a spring 39 is provided which acts to attain the purpose specified without interfering with the use of the handle, which may be readily depressed whenever needed. It is desirable to provide means to indicate in a positive manner to the operator after having adjusted the order-carrier to the width of the lumber that the same is exactly in the positoin indicated by pointer 19. For such pur- ISO pose a spring-actuated pawl 40, Fig. 2, and a toothed rack 41 are provided, the teeth o'l which are spaced to correspond with the graduations of scale 21. It in the exact position, the pawl after depression of the arm will engage one of these teeth or spaces, which fact the operator may readily test by attempting with the depressed arm to move the ordercarrier. the position of the order-carrier corresponds to the position indicated by pointer 19.

After any particular order is iilled the corresponding plug is simply removed Vfrom the order-carrier, whereupon operation ot the particular signal ceases. This latter as a whole may also rest removL bly on frame 16, which carries it, thus permitting it to be taken, for instance, to the oi'hce oi the establishment for rearrangement of orders. There might also be duplicate carriers, one taking the place of the other, &c.

It may be mentioned here that this device is only intended 'for use in connection with dimension-mills handling extensive orders, from ten thousand to fifty thousand pieces being a usual run of pieces at any particular size, so that a machine with its order-carrier once arranged for a series of orders may run for several days or weeks before rearrangement of the order-carrier becomes necessary.

It remains yet to allude to the electrical arrangement for operating the lamps thron gh the medium of the contact-pieces and which may be accomplished in several ways, a preferable one being the following: The entire order-carrier is arranged to carry current by being made of metal. To reduce the weight, a thin sheet of copper maybe used, resting on a backing of wood. The current is brorght to one of the track-rails 18 by a wire 42, and from there by a contact-piece 43 to the copper plate, whereby it is transmitted to any plugs occupying the socket-holes therein. At contact of these plugs with contact-pieces 26 the current passes 'from these latter to the lamps by wire 44. A wire 45 receives the outgoing wire from each lamp and carries the current back to the circuit. The use of electricity for operating the signals permits possibility of various additional features. VJ here fractions of inches are used on scale 23, varicolored lamps may be used for inches, halfinches. and quarter-inches to prevent mistakes and permit quick perception..

The characters of orders as to quality with reference to admission of defects or as to their urgency may be indicated bythe action of the lamps, which may show a steady light, or a flickering one, and in this latter case the lights may vary with a slowly-pulsating throb or a quick vibration. One might indicate stock-orders not very important. The other may show orders wanted, but not urgent. The last might mean a hurry order to be given preference over all others. Thus,

Inability to do such shows him that me'nt oi the order-carrier to the width et a certain piece of lumber there should be among the si glial-lights showing up a quickly-vil)ratt ing one,indicat ing a hurry order, the operator i in placing the marks would give it preference. l Should there be no such light, he wouldnext i prefer a size indicated by a slo\\'ly-pulsating l one, should there be such, and ii'nal ly he woul d lconsider the stock-orders. As to quality, g certain signals might mean that the piece must be entirely detect-clear, or so on one side only. Such an arrangement requires, ol' course, independent circuits 'lor'each kind of light. This may be done by having independent order-carriers, one behind the other, but moving together, and a bridge l5 or row of signals for each, as shown in Fig. S. A plug for a certain order would. then be placed I to illustrate: lit, for instance, after adjustl nature of the order. Since the carriers move together while the width of the lumber is determined by nnmipulation of pointer 29, it is clear that at the particular width signal-operl ating contact is made b v either one ol the l carriers. ,lhellickeri'ngo'lthelampsisreadily obtained by .inserting a customary circuitbreaker into the particular circuit, the action of which is regulated according to the arrangement desired. This variety as to the action ol' lights may also be obtained in one order-carrier by arranging the contact-pieces accordingly and by using two copper plates, as shown in Fig. t5. 27 shows the plugs, as described before, receiving current -l'rom the upper plate. 27" is a plug isolated from the upper copper plate and receiving current from the lower plate. 27h is a plug ol' rubber or other non-conducting material and transmitting no current trom the order-carrier, but serves merely to bring contact-piece 2o into contact with a supplementary contactpiece 26 above,l which forms part oi'V a ditl`er- I ent circuit.

The circuit breaker above mentioned would be inserted and form part o'l that particular circuit which is to control the Vflickering lights. its particular position within the circuit vis immaterial and may be in wire 42 or in wire 45, shown. A. commercial flasher obtainable in the markets, like the socalled 1). & L. ilasher, might be used, or one as shown in Fig. 9, involving the action of a magnet 47 as opposed by the action o'lIV a l spring 4S, the same as in a call-bell, and the t operation ol which is readily understood. l The rapidity of the vibrat ions is gagcd by the l strength. oi the spring.

lt is evident, since the operation of the signals is brought about by the manipulation 'ler adjustment of one part with reference to another, oi' which each carries contactpieces, that it is immaterial which one of the parts involvedto wit, the. order-carrier or l the bridge-is manipulated.

in the particular carrier and according to the The operation has already been explained; but it may be shortly summed up as follows: A piece of lumberto be subdivided is placed in position with one of itsedges against scale 23 and with its left end opposite the zeromark thereon. The order-carrier is moved outwardly from its normal position and toward the operator, the extent of the movement being equal to the width of the lumber, and which is determined by lowering handle 28 and by placing its pointed part 29 against the other longitudinal edge of the lumber, as shown in Figs. 2 and 3. The operator now watches for appearanceof signal-lamps operating due to the changedposition of the ordercarrier, and which signal shows him at once that pieces of the length indicated by the position of such signal are wanted, and opposite which signal he therefore places a .mark Having so marked out one piece, he now shifts the lumber to the left until the mark he placed on the lumber is o posite the zeromark of scale 23, after whic he repeats the operation. It ma be that in some cases two or more signa s spring up at the same time, as before mentioned, showing that various lengths are wanted of a certain Width. In such case the operator uses his judgment, taking usually pieces as long as they are obtainable with reference to the position of defects and so as to miss them. Should among the several signals be flickering ones, he acts according to their intended meaning as established by a selected code. If they indicate preferred or hurry orders, he gives them preference. Should nature or position of any defect prevent him from marking out a larger or preferred size, he can always help himself and select a size indicated by another signal, so that a readjustment or shifting of the lumber does not necessarily have to take place and no time need to be wasted with useess manipulations.
